there are two kinds of admission in polytechnics,
Admission for tertiary courses and admission for non tertiary course.
Since you did not specify,
I am assuming that you want to offer a diploma course which falls under the tertiary courses. For any polytechnic admission you need just 5 subjects, 3 core and 2 electives. so the e8 will not matter if you are not going to do a mathematics related course. Also, the d7 in maths and physics will be accounted for by writing an entrance exams that will be organize for those who do not explicitly meet the application requirement. if you pass the entrance exams then the school will admit you.
In summary, i am saying that you can apply.
